Pulmonary artery enlargement as a predictor of long-term prognosis in patients with resected early-stage non–small cell lung cancer

In patients with resected early-stage non-small cell lung cancer, those with preoperatively pulmonary artery enlargement had a poorer overall survival than those without, possibly attributed to a higher non-lung cancer-related death incidence. Measuring the preoperative PA/A ratio might be a useful tool for risk stratification, and selecting sublobar resection for these patients could improve the long-term prognosis.
